The flashcards below were created by user hgienau on FreezingBlue Flashcards. What would you like to do?


  1. Motions that occur in the saggital plane and frontal axis
    flexion and extension
  2. Motions that occur in the frontal plane and saggital axis?
    abduction/adduction, radial/ulnar deviation, inversion/eversion
  3. Motions that occur in the transverse plane and vertical axis
    internal/external rotation, horizontal abduction/adduction, supination/pronation, right and left trunk rotaion
  4. Define osteokinematics
    • relationship of bony movement
    • discusses bony movement of a joint
    • visible movement of a joint
  5. Define arthrokinematics
    • relationship of joint surface movement
    • must have arthokinematic motion to have osteokinematic motion
  6. Define the axial skeleton
    cranium, face,vertebral column, and sternum
  7. Define appendicular skeleton
    extremities
  8. List the functions of the skeletal system
    • Support- for soft tissues of the body
    • Movement - bones serve as levers and joints as fulcrum
    • Protection - vital organs
    • Mineral Storage - calcium and phosphorous
    • Provide shape
  9. Define a synovial joint
    • diahthrosis
    • plane, hinge, pivot, cndyloid,saddle, ball and socket,
  10. Define a non-axial joint
    • plane joint
    • relatively flat joint surfaces
    • glide over one another
    • no degrees of movement
    • example: intercarpla or interstarsal joints
  11. Define uniaxial
    • one plane, one axis
    • one degree of freedom
    • hinge or pivot
    • ex: elbow, knee, or interphalangeal
  12. Define biaxial
    • 2 axes, 2planes
    • condyloid or saddle
    • ex metacapophalangeal, and radiocarpal
  13. Define Triaxial
    • 3 axes, 3 planes
    • ball and socket
    • hip and soulder
  14. Types of arthrokinematic motion
    • spin - rotary movement, one surface is fixed and the other surface spins on it
    • Roll - one joint surface rolls on another
    • Glide - Linear movement, parallel motion
  15. Convex-concave law
    • concave joint surfaces move in the smae direction as the joint motion
    • Convex joint surfaces move opposite the direction of the moving body segment
  16. List the functional Characteristics of Muscle Tissue
    • Irritability - react to stimnulus
    • Contractility - ability to shorten or contract
    • Extensibility - stretch
    • Elasticity - rocoil
  17. Active Insufficiency
    • when a muscle reache3s a point where it can't shorten any farther
    • occurs when muscles are contracting
  18. Passive insufficiency
    • When a muscles can't be elongates any farther without damage to the fibers
    • occurs to the muscles being stretched
  19. Types of Muscle Contraction
    • Isometric- fixed, no motion
    • Isotonic - concentric shortening
    • eccentric- lengthening
  20. Roles of Muscles
    • Agonist- muscles or muscle group that causes the motion
    • Antagonist - muscles tat performs the opposite motion
    • Cocontraction - when agonist and antagonist contract at the same time
    • Stabilizer- muscle group that supports or makes firm, a part and allow the agonist to wrok more efficently
    • Neutralizer - prevents unwanted motion
    • Synergist - works with other muscles
